Absolutely love playing with Sims. Totally addictive. It's the only video game I play.

It's such a lovely and fun way to play "God" You can make or break your little people, even kill them off if you dont like them. Watch as they learn to talk (more gibberish than before) or even pee on the floor because you didnt click on the bathroom icon. It becomes uite addicting.
